I write most of my projects in Python but I don't think that's a good option for beginners, sure it's easy but you wouldn't understand the basics of programming with it, this also applies to PHP and Javascript.

With C you will learn the "traditional" programming, you have to declare variables, allocate memory, learn the datatypes, structures, etc...

In my case I started with Pascal some years ago, it's also a good starting point but I think C is the better language for beginners.
